How much does the 2018 Mercedes-Benz G-Class cost?

Prices have softened 8.27% compared to this time last year, making it a favorable time to shop this model year.

There are 329 listings available, which gives you a workable amount of inventory to compare before you commit.

If you find a listing below $80,767.15, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2018 Mercedes-Benz G-Class a good car?

The 2018 Mercedes-Benz G-Class stands out because it represents the end of the original design’s long run, and that old-school, boxy character is a big part of the appeal. It began life as a military vehicle and evolved into a luxury off-roader with a reputation for being both iconic and highly capable.

For you, that means this model makes the most sense if you want a vehicle with unmistakable presence, rugged roots, and serious trail ability, even if most owners are drawn more to its style than to off-road use. The buying guide also describes it as a hyper-expensive machine, so the appeal is as much about exclusivity as utility.

Market availability: 28.6% of listings are priced as good or great deals.

Is the 2018 Mercedes-Benz G-Class reliable?

The 2018 Mercedes-Benz G-Class is described as generally very reliable, but ownership comes with expensive maintenance and repair costs. The guide also notes that fuel economy is a weakness.

For used buyers, that means long-term ownership risk is less about frequent breakdowns and more about the cost of keeping a complex, high-end SUV in top shape.

What should I look for when buying a used 2018 Mercedes-Benz G-Class?

At 73.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should run a vehicle history report before you get serious about any listing, then prioritize a pre-purchase inspection from a shop that knows luxury SUVs. Focus on condition, maintenance records, and signs of hard use, since this model’s appeal often overlaps with expensive repairs if prior ownership was rough.

What is the 2018 Mercedes-Benz G-Class's resale value?

The current average of $80,783 sits slightly below last year's $88,068.

That price movement suggests the market has cooled, which can help you buy more selectively now. For a future seller, it also means resale value may depend heavily on condition, mileage, and how well the vehicle has been maintained.

Should I buy a 2018 Mercedes-Benz G-Class or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 28.6% of listings are priced as good or great deals.
• At 73.6% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 8.27% compared with last year.

Consider the 2019 if:

• At $108,370, the 2019 costs more than the current year's $80,783 average.
• It brings a thoroughly upscale cabin and a first full redesign in 40 years.

The bottom line: If you want the original G-Class character at a lower average price, the 2018 is the stronger value play. If you want the newer-generation experience and can stretch your budget, the 2019 is the better premium alternative; price-sensitive buyers should start with the 2018 and shop condition carefully.
